Although they occasionally duel on the ABC talk show "The View," the real duel between Barbara Walters and Elisabeth Hasselbeck took place Tuesday night when the two hawked their new books on separate cable networks. Walters retreated to the safe confines of fellow news veteran Larry King, while Hasselbeck felt more at home in the conservative confines of Fox News Channels' Sean Hannity.

The juxtaposition illuminated some of the main differences between the two women: Walters and King talked about aging in the news business while Hasselbeck and Hannity talked gluten diets and Republicanism.
